ABSTRACT

INTRODUCCIÓN La suplementación habitual del hipotiroidismo se basa en la monoterapia con levotiroxina, sin embargo, algunos pacientes persisten con síntomas atribuibles al déficit de hormona tiroidea. Debido a esto se ha planteado que el uso de un tratamiento combinado con liotironina y levotiroxina otorgaría un mayor beneficio. MÉTODOS Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES Identificamos tres revisiones sistemáticas que en conjunto incluyeron 12 estudios primarios, todos correspondientes a ensayos aleatorizados. Concluimos que la adición de liotironina al tratamiento del hipotiroidismo tiene un efecto mínimo o nulo sobre fatiga y calidad de vida. Probablemente tampoco mejora estado de ánimo, dolor ni función cognitiva, y no reduciría el peso corporal.


INTRODUCTION The usual supplementation for hypothyroidism is based on monotherapy with levothyroxine. However, some patients persist with symptoms attributable to the deficit of thyroid hormone. It has been suggested that the a combined treatment with liothyronine and levothyroxine would provide a greater benefit. METHODS We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified three systematic reviews including twelve primary studies overall, all of which were randomized trials. We concluded that the addition of liothyronine to the treatment of hypothyroidism has minimal or no effect on fatigue and quality of life. It probably does not improve mood, pain or function cognitive, and it would not reduce body weight.
